IMPROVEMENT IN CHURNS.

To all whom it may concern Be it known that I, IRA J. RYERSON, ofPierceton, in the county of Kosciusko and State ofIndiana, have inventedan Improved Churn; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which Figure 1 is a side elevation of my improvedchurn. Fig. 2 is an end elevation of the same. Fig. 3 is a centralsectional elevation of the lid of the churn, and a broken section of theadjoiningparts. Fig. 4 is a plan View of the guide through which thedasher-rod operates, and a horizontal section of the dasher-rod. Fig. 5is horizontal section of the dasher-rod, holder, and regulator. Fig. 6is an elevation of the pitman-wheel.

The object of my invention is to attach to the lid of the commondasher-churn such mechanical appliances as will easily operate thedasher, and by means of which the length of the dasher may be adjustedso as to suit the depth of any ordinary churn-barrel and the quantity ofcream used in the same, and to arrange the gearing of the churn so thatthe dasher may be made to move up and down in the usual manner byturning the crank attached to the gearing, and so to arrange the variousdevices attached to the lid that the same, including thelid, may betaken off from the barrel of the churn after the churning process,leaving the dasher in the barrel, with which to gather the butter.

A further object of my invention is to place the guide which regulatesthe dasher above the lid of the churn instead of in the churnbarrel. Itis well known that it requires two bearings or guides in order to keepthe dasherrod in a vertical position when operated by the commonpitinan, and that it is a common practice to use the lid of the churn asone guide, and to put the other guide inside of the churnbarrel, andalso that the friction which results from the operation of the dasher ontheinside guide is sufficient to generate an oily substance in the creamwhich is very injurious to the butter. This difficulty I obviate byplacing a guide above the lid of the churn instead of in thechurn-barrel, and also leave the inside of the churn-barrel free fromany obstructions that would interfere with taking out the butter andcleaning the churn. It will be 'seen that this gearing may be readilyattached to any upright dasher-churn barrel, whether of wood or stone.

To enable others skilled in the art to make and use my invention, I willdescribe the method of constructing and operating the same.

A represents the common wooden churnbarrel, to which my invention isattached.

L shows a portion of the churn-barrel broken out to give a view of thedasher. G represents the lid of the churn, to which my device isattached.

6, Fig. 3, shows the manner of rabbeting the lid so as to allow a largeportion of the same to project down into the churn,fo'r the purpose ofsecuring it to the churn-barrel without any additional fastening.

7 represents the beveling of the rabbet of that portion of thelid whichis hung by means of the hinge H so as to open, as shown bythe dottedlines Y.

F shows the part attached to the lid 0, for the purpose of giving asuitable foundation for supporting the frame E. This frame E is used tosupport the shaft U of the drive-wheel S, and the shaft V ofthe pinionT.

B shows the pitman-wheel attached to the shaft V outside the frame E,and in a convenient position to operate the pitman K by means of thewrist 8.

m represents a metallic plate attached to the 1 lid of the churn O bymeans of the screws a, for the purpose of giving a sufficient support tothe inclined standards P. These standards P pass through the plates m bymeans of a tenon and rivet in the usual manner.

Q represents the upper guide,whieh is secured to the inclined standardsP by brazing, soldering, or other permanent means, This guide Q iscircular, and the flasher-rod B passes up and down through it when thechurn is operated.

G represents the dasher holder and regulator, to which the upper end ofthe pitman K is attached by means of the wrist 2 and nut z. Thisregulator G has a circular opening,through which the dasher-rod is madeto pass when regulating the dasher D with reference to the depth of thechurnbarrel A and the quantity of creamused in the same, as shown atFig. 5. The dotted lines X show the point to which to pass through theguide Q in regulating the length of the rod B, by means of the regulatorG, to suit a churn-barrel of less depth than.-

that shown at A, Fig. 1.

I shows the thumb screw, inserted in the regulator G, by means of whichthe dasher rod B is held firmly at the required point.

Fig. 6 shows the pitman-wheel, in which are made the holes 8 and 4-, ineitherof \vliich the wrist 8 may be inserted.

The object of the additional hole4 is to give a shorter stroke to thepitman K when the masher-rod is regulated by means of G to-achurn-barrel'of'less depth-than that shown at I standards P, guide Q;with-thedasher-rod B A, Fig. 1.

It will be seen from the abovedescript-ion that the length of thedasher-rodBand the stroke'given by the pitman=wheel R will'allow mydevice to be attached to any ordinary above described it'is'necessary'toraisea part .ing process is complete.

of the lid, as shown by the dotted lines Y, Fig. 3;. Then fill thechurn-barrel not to exceed three-fourths full with cream. Then turn thecrank W in either direction until the churn- The operation of thegearing attached to the frame E, being in common use, needsno-explanat-ion. The thumbscrcw 1 must then be loosened in order thatthe regulator G may be moved up and taken offthewdasher-rodB, and thelid 0, including the gearing, may be lifted up from the line 9 in thedirection of the darts 10, so as to leave tlie dasher and rodin thechurn-barrel, for the purpose of gathering the butter.

Having thus described my device, what I ,claim, and desire to secure bylletters Patent of the Unit'ed States, is-

The" arrangement and combination ofi't'he and regulator Gr,substantially as described and set forth.
